I've always run wifi when I have it available, and use llama to automatically turn off mobile data when I connect to wifi. I assumed this would help with battery life, but in wondering if just ruining with 3g would be better.

It depends on certain situations. With 3G you have to reach a tower and it's going to use a lot of power trying to get a good signal. WiFi on the other hand doesn't have to. However. if WiFi is left on, it'll keep searching for a connection, which can drain the battery faster.

That being said, when I have access to WiFi I turn it on and use it. Otherwise WiFi is off.

Thanks for the info. I've been doing some testing, and it seems leaving both on when wifi is available is fine, and turning off wifi when away does drain faster than at home, but slower than leaving both on.

Also, my battery life seems to have improved significantly since I disabled llama. Maybe I was being too aggressive with my settings?
